Asynchronous or induction generators rely on slip to produce output; they are widely used in wind farms and can be voltage regulated by changing the slip or adding reactance. Nuclear power plants produce steam that turns a turbine connected to a generator; reactor physics, safety systems and the coupling of turbine and grid are essential. DC generators give direct current but need commutation devices; rectifiers convert AC to DC for use in power supplies.
Hydroelectric stations use Pelton, Francis or Kaplan turbines that harness water flow; calculations of hydraulic head help design the plant layout. Renewable sources such as wind turbines and solar PV panels convert kinetic or light energy into electricity; inverters adjust the output so it can be fed to the grid. Thermal power plants use coal, gas or combined cycle processes; steam turbine thermodynamics and generator synchronization improve efficiency and reliability.
